Hi Rusty and
to the forum.
To reverse the motor's default direction of rotation from the standard wiring, the
Blue and
Yellow Phase wires must be swapped over on the controller terminals, and the
Green and
Yellow Hall sensor wires must be swapped on the Hall sensor connector.
Of the 36 different Hall and Phase wire combinations there are only 3 that will correctly reverse the motor's direction of rotation, and if you are not using one of these 3 correct combinations, then the motor will not run properly.
I suggest that you set the wires as mentioned above and see if it cures the problem.
